Excuse my ignorance - what are the Pauline epistles ?
They are the letters ("epistles") written by St. Paul to the early church. A great portion of the New Testament is composed of the Pauline Epistles.
Someone beat me to the punch--they are the books written by Paul in the New Testament... Romans, Corinthians, etc. Paul has a lot to say about the subject of love & marriage and balances it all with how & why singlehood can be truly a gift from God.
